Long-term deterioration of bone-conduction hearing level in patients with labyrinthine fistula

Treatment using diffuse laser energy of cochlear and vestibular fistulas caused by cholesteatoma

“…Concern has been previously raised that long-term hearing in patients treated for cholesteatomatous fistulas may progressively deteriorate 10 . Our study does not, at this stage, include long-term assessment of hearing after laser treatment of cochlear and vestibular fistulas.…”

“…Finally, it is worth mentioning that a few prominent publications on this topic were excluded from being pooled into our analysis due to insufficient presentation of hearing outcomes in a detailed and meaningful manner sufficient to afford statistical analysis. 32-52 Some of these excluded studies had large subject numbers on exteriorization that would have partially compensated the discrepancy between number of subjects with matrix removal versus exteriorization that existed in our primary analysis.…”

“…Consensus opinion indicates that manipulation of a cochlear fistula is associated with sensorineural hearing loss, whereas semicircular canal fistula appear to have the same risk of hearing loss with matrix removal or preservation . Long‐term complications of the method of repair are less commonly discussed, though if a fistula persists, some suggest that a risk of future hearing loss remains …”

“…1 Long-term complications of the method of repair are less commonly discussed, though if a fistula persists, some suggest that a risk of future hearing loss remains. 3,13 Vestibular symptoms with labyrinthine fistula due to cholesteatoma are variable and depend on the duration of disease and remaining vestibular function. If the vestibular function is intact, the patient may be sensitive to pressure changes, though this is less likely if there is bulky disease in the antrum and an intact canal wall.…”
